The operations and settings that can be performed only in the Admin Viewer are explained. 
Magnifying Part of the Video (Viewer PTZ)
You can use the Viewer PTZ panel to magnify part of the 
camera’s video in the video display area. 
„Viewer PTZ
Viewer PTZ uses the digital zoom function to enlarge part 
of a video without using the camera pan, tilt or zoom 
functions.
This function allows you to enlarge part of a video when 
using the camera in a locked position, for example, during 
use of an intelligent function.

Drag the preview frame line to make the frame smaller, 
and a magnified view of the video in the frame will be 
shown in the video display area.
The preview frame turns blue when you drag it.

„Setting the Smart Shade Control
The smart shade control function differs from backlight 
compensation in that only dark areas are brightened while 
bright areas are kept intact. 
(1) [Smart Shade Control]
Select [Auto], [Manual], or [Disable].
(2) Adjusting the Smart Shade Control
When smart shade control is [Manual], set one of the 7 
levels from [1] (Mild) to [7] (Strong).
Example: If the background is bright and the subject 
is hard to see, this function brightens dark areas to 
make the subject clearer. 
In comparison to backlight compensation, smart 
shade control can reduce overexposure of bright 
areas. 
Note
 When [Auto] or [Manual] is selected for smart shade control, 
the video data size increases. 
 When [Manual] is selected for smart shade control, setting a 
high compensation strength may increase screen noise. If 
noise is noticeable, lower the control level.
„Setting the Focus
[Auto]  : Automatically focuses on the 
subject.
[Manual] : You can adjust the focus manually 
by pushing the  (far) and 
(near) buttons. 
Clicking [One-shot AF] will use 
autofocus to focus on a subject and 
then stop in manual focus.
[Fixed at Infinity] : You can set the focus so that it is 
fixed near infinity. 
„Setting the Exposure
Important
 [Auto] cannot be selected for [Smart Shade Control] if 
[Exposure] is set to [Manual].
 The [BLC] button is not available if [Smart Shade Control] is 
set to [Auto].

(1) Exposure Mode
Select from [Auto], [Manual], [Auto (Flickerless)] or 
[Auto (Shutter-priority AE)]. 
If [Auto] is selected for [Day/Night] under [Camera] in 
the Setting page (p. 43), select [Auto ], [Auto 
(Flickerless)] or [Auto (Shutter-priority AE)]. 
[Auto]
The exposure is controlled automatically.
[Manual]
The exposure is set by adjusting the shutter speed 
and gain values manually.
[Auto (Flickerless)]
In this mode, video flickering caused by fluorescent 
lights, etc., can be reduced. The shutter speed is 
automatically adjusted according to the brightness 
of the environment in which the camera is used.
[Auto (Shutter-priority AE)]
In this mode, the desired shutter speed can be 
specified.
(2) [Exposure Compensation]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the exposure 
compensation value desired can be selected from 
nine levels (-4 to +4) using the slider. 
To darken the video, select a negative value. To 
brighten the video, select a positive value. 
(3) [Metering Mode]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the metering 
mode can be selected from [Center-Weighted], 
[Average] or [Spot]. 
For an explanation on each item set in [Metering 
Mode], see [Metering Mode] in the Setting page 
(p. 42).
(4) [Shutter Speed] 
When [Manual] or [Auto (Shutter-priority AE)] is 
selected for [Exposure], select the shutter speed 
desired. If [Manual] is selected, set the shutter speed 
in the range of [1/1 sec] to [1/16000 sec] from a pull-
down menu. If [Auto (Shutter-priority AE)] is selected, 
set the shutter speed in the range of [1/2 sec] to [1/
16000 sec] from a pull-down menu.
When capturing a moving subject, selecting a higher 
shutter speed can reduce blurry video capture.
(5) [Slow Shutter]
You can set slow shutter if [Exposure] is set to [Auto] 
or [Auto (Flickerless)]. Select a value in the range of 
[1/2 sec] to [1/30 sec] from the pull-down menu.
As slower shutter speeds generate afterimages when 
capturing a moving subject, select an appropriate 
time according to the capture conditions. (6) [Gain] 
If [Manual] is selected for [Exposure], set a desired 
gain value. 
Moving the slider to the left decreases the gain 
(sensitivity to brightness) and darkens the video. 
Moving the slider to the right increases the gain and 
brightens the video.
„Setting White Balance
(1) [Auto] 
The white balance is adjusted automatically. 
(2) [Light Source] 
Select the light source from the pull-down menu below 
according to the condition in which the camera is 
used. 
For an explanation on each item set in [Light Source], 
see [White Balance] in the Setting page (p. 43).
(3) [Manual] 
The white balance is adjusted manually.
[One-shot WB]
This is used for forcibly locking the white balance to 
match the light source.
Important
 If the subject is a traffic signal or electronic scoreboard, etc., 
the captured 
video may flicker. 
In this case, try changing [Exposure] to [Auto (Shutter-priority 
AE)] and then select a shutter speed lower than 1/100, to see 
if the situation improves. 
 [Exposure Compensation] and [Manual] for [Exposure] 
cannot be selected if [Smart Shade Control] is set to [Auto].
 The [BLC] button is not available if [Exposure] is set to 
[Manual]. 
 Even if  [Exposure] is set to [Auto (Flickerless)], some screen 
flicker may still occur under unstable light source conditions. 
 When [Camera] > [Camera Control] > [AGC Limit] is set to 
[OFF] and [Exposure] is set to [Auto (Shutter-priority AE)], 
exposure compensation and backlight compensation will not 
be performed.

insertion/removal mechanism for the filter.
„Selecting the External Device Output
You can control external device output and display the 
current output status using an icon. Output can be 
activated and deactivated by clicking this icon.
„Registering Custom Settings
By registering settings for camera position, exposure, 
white balance, etc. beforehand, you can load settings 
using manual or automatic control.
Note

the Control for Admin menu can be saved.
[Smart Shade Control], [Exposure], [White Balance], [Image 
Quality Adjustment], [Day/Night]
 
[Pan/Tilt/Zoom]
[Focus]
Important
 Since the light source selection options are based on 
representative characteristics, proper colors may not be 
achieved depending on the applicable light source. In this 
case, use the [One-shot WB] function.
 If the subject looks greenish under mercury lamps in the 
[Auto] mode, select the [Mercury Lamp] mode under light 
source. If the video is still not shown in appropriate colors 
under mercury lamps when the [Mercury Lamp] mode is 
selected under light source, use [One-shot WB].
 When the subject has only one color, illumination is low, or 
when sodium lamps, mercury lamps and certain other 
fluorescent lighting are used, colors may not be adjusted 
appropriately.
 When [Day/Night] is set to [Night Mode] (including when it is 
set to [Auto] and night mode is judged to be applicable), the 
white balance function cannot be used.
 Notes on capturing video continuously day and night
If a subject that seldom changes is captured in a location 
where the light source changes gradually, such as when 
capturing a subject continuously day and night, appropriate 
colors may not be achieved. 
In the above case, applying changes to the video to capture 
will achieve the appropriate colors.

Important
If the viewer is exited in [Day Mode] or [Night Mode], auto day/
night stays disabled even if [Auto] is set in the setting page. To 
set auto day/night to enable, be sure to exit the viewer after 
setting [Auto].
